Extel SUNPOWER 60, Installation And User Manual

3GB

CFI EXTEL  SUNPOWER 60 - 04/2011 - V1

Automatic mode (08) 
The load is automatically controlled.
When the ambient lighting is low, the controller activates the load after 10 minutes.
When the ambient lighting is high, the controller deactivates the load. 

Manual mode (09)
The load is manually controlled.
A short press on the settings button (fig.3-1) activates the load. A second short press on the button deactivates 
the load (like a switch).

Dusk mode 
The load is automatically controlled. Two methods of operation are possible in this mode: 

1 lighting sequence (01 to 07):

 When the ambient lighting is low, the load is activated after 10 minutes for a 

defined period of time (see table). Once this period is ended, the load is deactivated. 

2 lighting sequences (10 to 39): 

When the ambient lighting is low, the load is activated after 10 minutes for a 

defined period of time (see table). Once this period is ended, the load is automatically deactivated. After this first 
sequence, a second sequence will be activated a few hours before sunrise. The load will be automatically deactiva-
ted as soon as the ambient lighting is high after 10 minutes. 

- Low level :  the voltage of the panel is less than 5V 
- High level : 

the voltage of the panel is greater than 6V 

This operating mode requires the length of the night to be known. The default value is 12 hours. This value will 

be recalculated by the controller according to the geographical area, which can take approximately 2 nights. You are 
therefore advised not to connect the load until after this adjustment period.   

See table below

d. Fastening the photovoltaic panel

- To ensure optimum performance the photovoltaic panel must be positioned in such a way that it is able to capture 
the maximum amount of solar power during the day. This means that the direction and angle of the panel must be 
calculated according to its installation location.

 Recommendation:

 installing the photovoltaic panel at a 45° angle facing towards the South provides the 

optimum conditions for capturing the maximum amount of solar power.
Use of a mounting bracket for fastening the selected panel angle to suit your needs is recommended (bracket not 
supplied).
- Select the appropriate location for installing the photovoltaic panel. The panel must receive the maximum amount 
of sunlight during the day and during different periods of the year in order to operate correctly. 
As a result the following checks must be made in order to verify whether the position selected is correct:
- Check that there is sunlight present for most of the daytime at the selected installation location.
- Check that the installation location is not surrounded by thick vegetation or anything capable of creating shade.
- Check that the direction and angle of the solar panel are correct.

 Warning: initially the battery charge will not be at the optimum level. It takes several days of 

charging for your system to reach optimum capacity.
